A process of UV image printing on a surface layer of a respiratory type mouth mask

Abstract

A process of UV image printing on a surface layer of a respiratory type mouth mask is provided. The process comprises following three steps: a step of computer mapping, a step of mold fixing and a step of UV printing. The UV printing process includes processing the image by using a computer mapping software, printing on the surface layer of the respiratory type mouth mask through a UV printer, and curing ink to a solid state by UV lights. During printing, the mouth mask is made of nonwoven fabric, and the position of the mouth mask is fixed through a matched mold, thus controlling the position of the image and effectively performing quantity production. Results of a color fastness test and a volatile organic compound test of the mouth mask show that the mouth mask is good in air permeability and waterproofness, harmless to health of customers, and capable of meeting economical, healthy and beautiful requirements of customers.

Description

technical field [0001] The invention relates to a UV printing process, in particular to a UV printing process for the surface image of a breathing mask. Background technique [0002] Due to the serious air pollution in recent years, smog occurs frequently. For safety protection, wearing a mask when going out has become a necessity for people's lives. [0003] In order to increase the ornamental value of the breathing mask, it is usually chosen to sew or print patterns on the surface of the mask. The techniques for pattern printing on finished respiratory masks usually include "thermal transfer printing" and "screen printing". Screen printing requires a special screen for each color of the pattern, so the cost is higher. In addition, it takes a long time and a lot of space for the ink to dry during the screen printing process. Thermal transfer printing refers to melting and printing the pattern on the thermal transfer paper on the surface of the printable material. This ...

Problems solved by technology

There is also digital printing directly on the raw material of the breathing mask in the market, but this method cannot control the position of the picture, and the printed picture can only present a repeated wallpaper style

[0004] In 1997, commercial UV printing machines were introduced, and foldable masks appeared long before that. However, in the past 17 years, although both technologies have been widely spread, no one has chosen to apply UV printing technology for protective masks.

And the world's leading company in the UV ink and printing industry - Liseda Company released the "Ultraviolet Curing Ink Technical Manual" to explain that UV technology is not suitable for long-term outdoor textiles that are continuously affected by weather and humidity

Liseda UV ink experts also clearly pointed out that since UV ink cannot be fully cured on breathing masks and is too close to the breathing area, it is not suitable for printing on breathing masks
